Spotted
A slender, medium-sized cuckoo named for the distinctive yellow on its lower mandible. It is known for its rapid, knocking call and preference for dense woodland.
Where to spot
Woodlands, forests, and dense thickets, often near water, across North, Central, and South America.
How to spot
Listen for its characteristic rapid, knocking call that slows towards the end. It can be hard to spot as it moves stealthily through dense foliage, but look for the striking yellow lower mandible when it pauses.
When to spot
Breeding season (late spring to early autumn) in its northern range. Most active during the day, especially after rain.

The Yellow-billed Cuckoo is famous for its diet of caterpillars, including fuzzy, unpalatable ones that most other birds avoid. It even sheds its stomach lining periodically to get rid of accumulated caterpillar hairs!
